How it compares

Three systems in the 450–500L range. The WB-Advant 500 Mini3 offers the best combination of value, features, and warranty — 500L WRAS-confirmed storage, 50 l/min variable speed, WiFi, and an outstanding 10-year tank warranty at the mid-range price. The Powertank offers Fluid Category 4. The DAB Esytank 500 is the same Esybox Mini3 pump in the DAB-designed integrated system with 480L useable storage.

Which should I choose?
WB-Advant 500 Mini3 — the outstanding choice at £896 + VAT. More storage than the Powertank (500L vs 450L), higher flow (50 vs 40 l/min), variable speed, WiFi and voice control, WRAS confirmed, and an unmatched 10-year tank warranty. Significantly cheaper than the DAB Esytank 500 with identical pump performance. The right choice for the large majority of potable water applications.
Powertank SLIMLINE 450 Fixed — choose only for Fluid Category 4 compliance, or if the upright slimline format specifically suits your installation. 450L, 40 l/min. £818.55 + VAT.
DAB Esytank 500 with Esybox Mini3 — same Esybox Mini3 pump with 480L useable storage in the DAB integrated Esytank system. Choose if you specifically want the DAB Esytank ecosystem — for example, to expand capacity using the DAB coupling kit. WRAS not stated on product page. At £1,051 + VAT it is £155 more than the WB-Advant 500 Mini3.

Frequently asked questions

How much does it cost and how quickly is it delivered?

£896.00 + VAT (£1,075.20 inc VAT). Delivery is typically 1–2 working days. Contact us via WhatsApp or phone to confirm availability before ordering.

What is the Advant tank and how does it differ from a slimline tank?

The Advant tank is a UK-manufactured, 100% rust-proof WRAS-approved tank in a wider, lower-profile format (650mm W × 870mm L × 1200mm H) rather than the tall narrow cylinder of a slimline. It carries a 10-year warranty — twice the 5 years on slimline formats. The Advant format is ideal for garages, plant rooms, and spaces where a squat, wide installation is more practical than a tall cylinder. Note: the 870mm length means it is not suitable for spaces where only a narrow cylinder would fit.

What is the difference between this and the WB-Advant 500 Esybox?

Both use the same 500L Advant tank with 10-year warranty. The pump differs. This system uses the Esybox Mini3 — 50 l/min @ 3 bar, 5.5 bar max, 45 dB(A), WiFi. The WB-Advant 500 Esybox (£1,210 + VAT) uses the full Esybox — 80 l/min @ 3 bar, 6.5 bar max, 43 dB(A), WiFi and H2D. Choose the Mini3 for moderate demand; the Esybox for higher flow requirements.

How does the mains connection work?

The mains supply connects directly to the tank via the pre-fitted ¾” ball float valve. The tank fills automatically and provides a storage buffer. The Esybox Mini3 draws from the tank and boosts pressure throughout the property. A minimum of 0.5 bar incoming pressure is required.

What warranties are included?

10 years on the WRAS Advant tank and 3 years DAB warranty on the Esybox Mini3 pump, when purchased from Anglian Pumping Services.
